Where did that water come from before it came out of the pipe? This lesson provides students with a hands on discovery session all about groundwater and its journey from the sky through the earth and up to your sink. Students love the opportunity to create their own delicious edible model aquifer, though they just might enjoy adding the "pollution" a little too much!
What is so fascinating about bubbles? Why do we love to chase them and create them and pop them as soon as we can? Is it the precise spherical, round ball, shape, the incredibly fragile nature of the thin soap film, the beautiful colors that swirl and shimmer, or most likely, a combination of all these? In this unit students play with bubbles for a purpose, hypothesizing and determining the strongest bubble formula, using color to measure their thickness, solving bubble mysteries, constructing square bubbles and geometric suds, determining bubble chemistry, making elephants toothpaste, bouncing bubbles, creating super strong bubbles, putting students in a bubble, creating CO2 Sandwiches, and much much more.
